∠1 = 40
∠1 and ∠2 are on the same line and hence, they are supplementary angles.
∠1 + ∠2 = 180
40 + ∠2 = 180
∠2 = 180 - 40 = 140
Hence, m∠2 = 140.
Answer:
9/41
Step-by-step explanation:
The base line is
The square root of (41*2-40*2),=9
Thus, cosC=9/41

Answer:
Perimeter of given regular hexagon is <em>48.5 ft</em>.
Step-by-step explanation:
Let <em>ABCDEF</em> be the regular hexagon as shown in the attached figure.
<em>O</em> be the intersection point of the diagonals <em>EB</em>, <em>FC </em>and <em>AD</em>.
As per the property of regular hexagon, all the 6 triangles formed are equilateral triangles.
In other words,
are equilateral .
Area of an equilateral is defined as
:
Where <em>a </em>is the side of .
Area of hexagon =
We are given that area of hexagon = 169.74
Let <em>s </em>be the side of hexagon.
A regular Hexagon is made up of 6 equal sides, so
Perimeter of a regular hexagon =
Perimeter =
So, perimeter of given regular hexagon is .
"Difference" means there are two numbers, and if you miss <em>that</em> clue, then
the next word, "between", should alert you to the fact that two numbers are
required. The difference between one number is a lot like one scissor, one
tweezer, one pant, and the sound of one hand clapping.
